Sorry if I am being negative here. But this system feels like the opposite of how the current skill system i supposed to work - change skills when you want for different situations like MP and single/multiplayer games.

With this you are locking yourself to one build... Or am I missing something?

Probably you are missing something

It's quite the opposite you wrote eheh

With the current system if you want to change build and consequently the skill-affixes on your gear, you have to change all pieces of gear that has the "old-skill-you-had-affix" into "new-skill-you-want-to-try-affix".

With my suggestion you have simply to pay the mystic to change that affix into the one you want without the need to change gear.

Yeah, well I don't like the idéa of changing it at all I guess... But then I don't have that kind of gear now either.

So every time I decide to play differently which may be 5 times one evening, I have to pay to change my gear? For example if I play one build solo MP10 and another multi MP8.

It won't change anything for you.
If you don't have any item that gives you a bonus to a skill you will be the same as now.

On the other side if currently you have at least an item that gives you a bonus to a skill, if you want to change build you can but you have a wasted affix (because you can't change that affix to influence the new skills you will be using) unless you buy or change that item to another one that influences your new skills.

My idea "fixes" that.
Unless you are ok with having a specific "set of items" for every skill/build you want to use.

Well, I do have Inna's 4-set bonus. The difference though is that if something is impossible to change, you don't care that much because you can't really do anything. But if I can do something I feel like I have to to be optimal.

Also I feel that skills bonuses/powers should be more common on items for your suggestion to make sense. But that would make all your items locked to a specific build.

I think this is a great idea. Though I also think it's a little complex, and it could be simplified and improved in some aspects.
I don't see why the Mystic should be involved in enhancing skills and runes, she should only enchance and improve items, not skills.
My suggestion is to give the player a "Nephalem Power Tree", where he can spend "Nephalem Power" points to improve different skills and runes. In order to get "Nephalem Power" points, the player should first equip items with a "+X to Magic Power" if he's a wizard, "+X to Mighty Power" if he's a barbarian, etc.
For example: a barbarian could spend 3 points improving Frenzy damage, and once he spent 3 points on the skill, he would unlock another level, where he can also improve the different runes, like "increase maniac bonus to 5% per stack", or "increase the chance of triggering Sidearm to 35%", etc.
To be able to do that, the barbarian first needs to have 4 Nephalem Power points. Let's say he equips a weapon with "+2 to Mighty Power", a ring with "+1 to Nephalem Power", and a belt with "+1 to Mighty Power". If he spends all 4 points, and then unequips the belt, he would instantly remove the last point he spent from the Nephalem Power Tree.
Another way to win Nephalem Power points could be by Paragon Levels, let's say you get 1 point every 10 Paragon Levels, so you will have 10 Nephalem Power points at Paragon 100. This would be another motivation for players to level up to Paragon 100.

So, to make it short: I don't think the Mystic should be in charge to improve skills and runes. Instead, we should have a Nephalem Power Tree, where you can spend these points that you can get by item rolls or by Paragon Levels, in order to improve your skills and runes =)

Edit: oh, and I really loved the idea to grant Magic Power, Spiritual Power, Mighty power, Dark Power and Tribal Power as full set bonuses. That way people will start wearing full sets once again, and not only 2-3 pieces (because 2-3 pieces bonuses are even better than 4-5 pieces bonuses...)

I like your suggestions, but like the previous ones, they feel a bit too complex for the fast paced idea of Diablo 3, it would be an awesome feature for a RPG or MMO, but I wouldn't personally want this, at least, at that level, in Diablo 3.
